HPMC E5 is a cellulose-based polymer commonly used in film coating, wet granulation, and hard capsule production. It is nearly insoluble in hot water, acetone, anhydrous ethanol, and toluene, but dissolves in cold water to form a colloidal solution. HPMC E5 is classified as E type 2910, with an average methoxyl group content of 29% and an average hydroxypropyl group content of 10%. The JRS Pharma hypromellose product line offers a range of E grades, varying from low to high viscosity.

Start
↓
Raw Material Preparation (Crush the cotton into fine powder)
↓
Etherification (Combine Methyl Chloride with Propylene Oxide to complete the etherification reaction)
↓
Neutralization After etherification, the reaction mixture is neutralized, often with an acid, to stop the reaction and remove excess alkali
↓
Precipitation-The HPMC is then precipitated from the solution using alcohol (usually isopropyl alcohol or ethanol).
↓
Washing (to remove impurities and residual solvents)
↓
Drying (moisture control)
↓
Milling and Sieving (achieve the desired particle size for its intended application.)
